Description

Ceiling storage device for display device with extension arm

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device capable of storing a display device (Panel Display Device; TV, monitor, etc. made of a display panel such as LCD, OLED, etc.) on a ceiling. In the ceiling storage device of the device (hereinafter referred to as the "receiving device"), by the force of the moving device (motor, reducer, pulley, belt or string, wheels, recoil), guide tracks and supports (support roller, support arm, support) A display housing frame ("frame") having a variable-length arm along a trajectory regulated by a track (orbit) uses less space than a conventional device by the second type lever and the principle of balance. It is a device that moves easily with a small force and expands into a living space for storage or use in an internal space on a ceiling.

The present invention frees up the interior space occupied by a large display device unnecessarily by storing the display panel on the ceiling when not in use, thereby expanding the usable space in the room and enhancing the safety, usability and flexibility of the interior layout. An object of the present invention is to increase the viewing distance within a given indoor space to increase the viewable display panel.

In general, the ceiling storage of the display panel is based on a movement of changing the vertical position of the display panel to a horizontal position in order to overcome the limitation of the storage space.

An intuitive way to change the vertical position to the horizontal position is the hinge type.

In the case of a hinge type using a hinge fixed to the ceiling, the ceiling must be opened larger than the area of the display panel to be stored for storage, and there is a problem in that the inside of the ceiling having a larger area than the area of the display panel is exposed in the unfolded state.

In addition, in the case of storing the display panel on the ceiling using a hinge, in most cases, the principle of the lever (first, second, and third) is to be stored with the smallest force in principle.

However, the existing method using the principle of hinge and lever shows many problems depending on the size and weight of the display panel, the height of the ceiling to be stored, and the height of the display panel descending from the ceiling when deployed for viewing.

In case of using the first type and the third type, the display panel is large and heavy, the height of the ceiling is high, and the height of the display panel needs to descend from the ceiling, and the height of the operating space inside the ceiling is low. The force required to accommodate the phase shift in the horizontal direction is more than several times the force for vertically lifting the display panel.

In the case of using the second type of principle, the storage can be more easily carried out, but the strength point is located under the display panel, and a string (or strip) for lifting the display panel is exposed to the interior, thereby impairing safety and aesthetics.

Due to these problems, the conventional ceiling storage type display device is applied to indoors such as automobiles and airplanes by being utilized practically by using the first type or the third type of principle only for a small and light display panel.

In the manner of storing the display panel vertically lined horizontally as described above,

If you are using the first class of principles,

The force (f) required to receive the display panel is inversely proportional to the distance between the force point and the support point (l) and is proportional to the distance (m) between the support point and the operating point and the weight (g) of the display panel, which can be expressed as f = mg / l. .

If the space inside the ceiling is small and the height is low due to the narrow interior of the ceiling despite the storage of large heavy display panels in the room with high ceilings, the force (f) required to accommodate the display panels is simply to raise the display panel vertically. It is more than several times (m / l> 1) larger than the required force (= weight, g). Therefore, the ceiling storage device of the display panel using the hinge and the first kind of lever principle requires a drastically powerful power and mechanism when storing a large heavy display panel in a room with a high ceiling.

If you use the third kind of principle,

The required force can be reduced by increasing the distance between the point and the support point, but there is a limit in principle to increase it in a given space, and when it is increased above the height of the space, the point (or band or arm) that connects to the point is exposed indoors. There is this.

If you use the second kind of principle,

Even if the ceiling is high and the display panel is heavy, when the power point is at the bottom of the display panel, the force required for storage is less than the weight of the display panel, so the requirement for the device is low. However, the string required for operation is exposed to the room, which impairs safety and aesthetics. There is a problem.

In addition, in the hinge type using a hinge fixed to the ceiling, the opening area of the ceiling for storage is larger than the area of the display panel and is limited by the height of the exposed ceiling or the inside of the ceiling that is larger than the area of the display panel when it is deployed for viewing. There is a problem that the viewing distance is shortened by being spaced apart from the surface (wall or window, etc.).

The present invention is proposed to solve the above problems,

first,

It is a belt or a band fixed to the lower connection point farthest from the pulley and the support point, and it is possible to change the phase from portrait to landscape with little force by the second kind of principle and balance principle. As storage progresses, it operates with a small force,

By the balance principle, the position of the working point is moved in the direction of the supporting point during the movement of the frame to reduce the force required for the storage of the display panel. In the balance principle, the guide orbit controls the movement and stabilizes the storage position when the frame is bent in the opposite direction beyond the balance point.

second,

The distance between the power point and the support point is increased by the supporting arm, and the distance between the support point and the action point is close, so that the phase can be changed from the vertical to the horizontal position with little force by the second kind of principle. The structure supporting arm acts as a supporting point, so that the distance between the supporting point and the working point is closer to each other.

The guide orbit tracks the frame continuously while the display housing frame moves to distribute the weight of the frame and maintain the distance between the operating point and the force point to minimize the force required to change the phase.

The frame has an extendable arm at the top and is located on the tracks of the skids with the wheels of the slider, which reduces the indoor exposure range, enhancing safety and aesthetics.

The support (support arm, support roller) distributes the weight of the display panel and frame during operation to reduce the force required for operation and to enter the inner space of the ceiling where the frame is not opened down together with the pulley and the slipper. .

Considering the fact that the most force is required when moving from the viewing position to the storage position, a recoil is mounted on the hoist, guide track, and other elements to accumulate the repulsive force by gravity when it is deployed to the viewing position. It uses the accumulated repulsive force to reduce the burden on the hoisting machine when storage starts.

When deploying to the viewing position, fix the viewing position fixed point of the guide track, support arm and slide, lower connection point (strength point) to the viewing position, and when storing the fixed position of the guide track, support roll, band and pulley. Secure in the storage position.

The principle of application for the ceiling storage of display panels requires a small force, so even a low specification mechanism device can accommodate a large display panel in the interior space of the ceiling that is not opened down.

Since the interior space required for movement for storage and deployment is small, the freedom of installation position of the ceiling storage device is higher than that of the conventional method such as hinge type.

By the action of supporting arm, the frame can be developed close to the constraint surface (wall, window, etc.), and it can be deployed in the short side of the rectangular space or diagonal direction, so that the viewing distance can be far from the given space. It enables the viewing of large screens, and when operating according to the second kind of principle, the distance between the power point and the support point is far, and the distance between the support point and the action point is close to reduce the force required for operation, and it is deployed in the direction of windows or doors. It can increase the utilization of space.

Since the ceiling open area is smaller than the existing devices, the interior area of the ceiling that is exposed when deployed for viewing is small and the doors can be reduced by attaching doors, which is advantageous for aesthetics.

Even though it is operated by the second kind of principle, the band (or belt, band) is exposed to the outside during the operation of the device compared to the existing device, which is advantageous for aesthetics and safety.

Even if the size of the display panel increases to a certain size, there is no change in the ceiling space required for operation and it can be deployed low so that it can fit the lower limit of the viewing angle of the viewer when developing for viewing. This is easy.

One or more overlapping extendable arms and one or more joints or support arms that are flexible and can be rolled up. The height from the frame to the ceiling is twice the height of the display panel. Even the above high ceiling can be stored without changing the ceiling open area.

Since there is no structure that interferes in the front direction of the display panel (viewer's position) during the storage and deployment process, the decorative replacement bezel can be installed on the front side to improve the decoration and can be replaced frequently.

The storage position has a protective surface (silicon protrusions or a cushion pad) to prevent the screen from sagging due to long-term storage.

Through this effect, the present invention facilitates the ceiling storage of the display panel with a small force, thereby securing additional space in the interior, enhancing safety, increasing the degree of freedom of layout of the interior, and improving the aesthetics of the interior effectively. It is a useful invention that can be done.

An extension arm extending and contracting on an upper portion of the frame for fixing the display device; A strip or string (hereinafter referred to as a “strap”) fastened to the upper connection point and the lower connection point is fastened to the pulley and installed as a balance hanging on the pulley; Fastening the wheel of the frame located at the top of the frame to the track of the guide track; When the pulley is rotated while the frame is deployed in the viewing position, the belt connected to the lower connection point is pulled out by the rotational force, and at the same time, the belt connected to the upper connection point is released and the ratio of the lengths of both bands is changed so that the center of gravity of the frame supported by both rows is The display panel changes in phase from the vertical direction to the horizontal direction; Operating according to the principle of the second class lever with the guide point and the fastening point of the wheel as the supporting point and the lower connection point as the force point; The wheel on the upper part of the frame moves along the guide track and restricts the movement of the frame by moving the frame to the interior space of the ceiling to accommodate the phase change from the viewing position to the storage position;

Through the reverse process, there is provided a ceiling storage device for a display device having an extension arm deployed to a viewing position.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

In addition, the embodiment of the present invention is not limited to the scope of the present invention but is presented by way of example and various modifications may be made without departing from the technical gist of the present invention.

The basic diaphragm (FIG. 1) of the ceiling storage device according to the present invention will be described below with reference to a process of developing from the storage position (a) to the viewing position (b).

The storage device includes a hoist (Winch, 100), a guide rail (200), a display housing frame (300), a support (400), and a door (Door, 500).

The hoist (Fig. 2, 100)

* Motor (110), Reducer (120), Recoil (130), Pulley (140) or wheels, and parts of belts (or strings). Or it is composed of all, the main drive unit for moving the storage window.

The hoist has a maximum load when storage begins and has a recoil to mitigate it, which contributes to lowering the maximum load level of the motor.

       When working on the principle of the second kind of principle and the balance,

The hoist and frame 300 are fastened to the pulley (or string) fixed to the upper connection point 440 and the lower connection point 450 is connected in the form of a balance. Pulleys and belts are an important factor to reduce the power required by the principle of balance as the frame is stored with efficient force by the second kind of principle.

The pulley rotates in both directions by the force of the motor and lifts or draws the strip. There are many ways to fasten the belt to the pulley. When the belt fastening to the upper connection point and the belt fastening to the lower connection point are separated (Fig. 8-A), the winding direction (or the unwinding direction) should be opposite to each other (Fig. 8-B). At this time, in order to prevent tangling when the cord is wound, a wire lead guide (FIG. 8-bar) having a shaft structure moving by the diameter of the cord during one rotation or controlling the entry and exit of the cord may be used. Must be installed. In the case of a string, it may not be separated as in the above case, and if it is not separated, the string may be simply hung on the pulley (Fig. 8-) or wound (Fig. 8-). In the case of simply hanging, in order to effectively transmit the rotational force of the pulley to make a groove, the contact surface between the rope and the pulley is widened or have a chain structure (Fig. 8-M). In case of winding, it is advantageous to receive the force, but the line can interfere with each other in the process of operation, so the guide frame (Fig. 8-bar) or guide groove to control the entry and exit should be installed. In the case of crossing separate bands or strings (Fig. 8-D) and in the case of winding the strings, it is possible to lift more power points (as a result of the frame) by the diameter.

The upper connection point to which the belt (or string) is connected is a shock absorber 352 for adjusting the relaxation of the belt according to the position of the frame and the state of the extension arm 350 (extension) during operation and to increase the tension of the belt. ) Will be equipped. The tension (q) of the shock absorber should be stronger than the force (p) that pulls the mold in the transverse direction at deployment and weaker than the force (g) that the mold lowers by weight (p <q <g).

The belt is fastened to the slider (Slider, 360) and the support pull (Belt Pulley, 361,362,421) of the support arm (420) is stored in the frame (385) of the frame (Fig. 9-A) and exposed only above a certain height Minimize the exposed area indoors.

Guide tracks (Figs. 3, 200)

An important component that regulates the trajectory of the movement of the frame when the storage device is operating is the track 210 and the receiving position fixing point 250 and the viewing position fixing point 260 at both ends thereof. It is installed.

The guide track and the frame are connected to the frame wheel 340 is fastened to the track of the guide track, the frame is wheeled by the track of the guide track is moved in the track and the trajectory of the movement is controlled. The guide trajector 230 is compressed by the weight and the hoist of the frame when the frame is deployed to the viewing position, accumulates force, and serves as a buffer to prevent rapid deployment, and the maximum load on the hoist with repulsive force when the storage starts. Lower it.

The guide track prevents the frame from being oriented in the opposite direction when the frame exceeds the balance point according to the balance principle, and keeps the distance between the supporting point and the force point at the second lever continuously as the frame moves.

The trajectory of the frame whose movement is regulated by the guide track and the wheel 350 of the frame, and the support roller 410 and the support arm 420 is reduced so that the space occupied when it operates is small.

The frame (Figs. 4, 300) is

The display panel 600 is mounted to move the space for storage and deployment as a structure having an extension arm 350 having a track on the side 320, or the side and back 330 and the length is changed within a certain range. The frame is connected to the guide track by fastening the wheel 340 of the frame to the track of the guide track.

A band is fastened to the upper connection point 440 and the lower connection point 450 and the frame and the pulley are connected by fastening the band to the pulley.

The wheel 320 of the support roller 410 is fastened to the track 320 of the frame so that the lower limit movement of the frame is restricted when the frame moves for storage and deployment. 472 to fix the mold in the storage position (FIG. 1).

A slide car (or wheel; Slider, 360) is fastened to the track 330 of the frame, and the sliding car is fastened to the support arm 420.

Extension arm 350 is located at the top of the frame and the wheel 340 of the frame is mounted and lowers the height of the required space inside the ceiling when the frame moves for storage and deployment. Elongation and contraction within the limited range of the extension arm lowers the height inside the ceiling necessary for the movement of the frame and moves the frame for deployment so that the frame has a longitudinal phase with the support arm when the support roll is displaced from the side track.

The upper and lower parts of the extension arm have pulleys, and the upper pulleys have a structure for guiding the strip. A belt connected to the pulley of the hoisting machine is fastened to the upper pulley of the extension arm, and again to the lower pulley, and then fixed to the upper part of the frame. The belt thus fastened is accompanied by an extension arm when the frame enters the frame when the frame is moved to the storage position by the traction machine.

The extension arm, along with the support and guide trajectory, reduces the frame's movement trajectory to reduce the occupancy of the interior space when operating for storage and deployment, to reduce the area of the doorway of the ceiling, and to guide and guide the first to the viewing position A fixed point is formed and a third fixed point is formed by the weight of the frame and the display panel together with the support arm.

The extension arm may contract and extend, and may have a multi-stage structure when the ceiling to be installed is high (when the distance of the bottom of the frame extending from the ceiling to the viewing position is more than twice the height of the display panel).

When the frame is deployed to the viewing position, the first fixed point is formed by the viewing position fixing point 260 of the wheel and the guide track, and the second fixing point is formed by the support arm and the structural skeleton 900, and the support arm is 3rd fixed point is formed by the extension arm of the frame and the weight of the frame and the display panel.

When the frame is accommodated in the storage position, the wheel of the frame is seated at the storage position fixing point 250 of the guide track, and the first fixed point is formed, and the support roller and the track of the frame form the second fixed point. The slide and the track of the frame form the third fixed point and are fixed at three points. The extension arm contracts when the belt connected to the lower connection point is lifted by the pulley, and as the belt is lifted into the extension arm even though the belt connected to the upper connection point is pulled out by the pulley, the head of the frame is fixed to the guide track. Stay on the section.

The frame is moved by the rotation of the hoist, that is, by the rotation of the pulley, suspended by a pulley and a band (or string), and is operated by the principle of balance and the second kind of principle. The upper connection point is equipped with wheels 340 and the shock absorber of the frame to adjust the relaxation of the belt and increase the tension (tension).

A belt is fastened to a slide (or wheel; slider) 360 fastened to the track 330 and a pulley installed on a support arm fastened to the sliding car. The action of the sliding pulley (Belt Pulley) to limit the area exposed to the band to a certain height even in the movement of the frame for storage and deployment. Sliding cars, straps and support arms play an important role of easy storage into the in-ceiling space where the frame is not opened downward (FIG. 1 storage location).

The extension arm has an upper connection point 440 of the strip. The upper connection point is equipped with a shock absorber to adjust the string relaxation and increase the tension of the string according to the position of the frame and the condition of the extension arm (extended length) during operation. The tension of this shock absorber should be stronger than the force that pulls the mold horizontally when it is deployed and weaker than the force that the mold lowers by weight.

Supports (FIGS. 5, 400)

When the frame is moved, the upper and lower limit movements are limited to the support roll 410, and when the frame reaches the storage position and is fixed, the screen of the display panel is supported by the screen support 430 to prevent the screen from sagging. In addition, the guide track, the band and the lower connection point 450, the support arm 420 during the storage and deployment process is a support for distributing the load of the frame.

The support roller 410 is connected to the frame by fastening the wheel 411 to the side track of the frame, and when the frame moves in the process of storage, the frame is supported so as not to sag more than the lower limit and the weight is distributed to the storage. When the required force is reduced and the frame passes the weight balance point, the load is transferred to the opposite side to reduce the force required for operation. When the storage is completed, one of the storage fixing points is formed to maintain the storage position without a separate locking device.

The lower side of the support arm 420 is fastened with the sliding (Slider). The support arm prevents the sliding car from flowing down the back of the frame by gravity due to the structural skeleton (900) and the elastic structure (spring, gas spring, rubber band, etc.) fastened to the support arm. The support arm works with the fastened sliding car, the back track, the wheel of the frame, and the guide track to act as a support for pushing the frame when the frame is stored in the inner space of the ceiling that is not opened downward. (Structure, 900) is formed in one of the viewing position fixed point supporting the frame together with the back track of the frame, the sliding difference when deployed to the viewing position.

If the height from the bottom of the frame to the ceiling is more than two times higher than the height of the display panel, when you extend the length by connecting two or more support arms with joints, or by extending the length with a string or band that can be wound by the pulley, It can be stored through the ceiling opening of the same area.

*

      The doors (Figs. 6, 500) are

The door 510 opens in front of the display panel and the door 520 opens behind the display panel during the storage and deployment process. The two doors can be folded up and down using the rails 530 and 540, or can be opened and closed down by hinges to reduce the space occupied when opening and closing the doors. The door that opens in front of the display panel is closed when the frame is in the viewing position or the storage position to reduce the open area 560 of the ceiling 550 when the frame is in the viewing position. The door that opens behind the display panel is closed only when the frame is in the stowed position.

Display with more than

The pulley rotates the frame at the storage position (a) and lifts the belt to pull the upper connection point 450 to move backward.

The wheel of the frame moves along the trajectory of the guide track and develops as the required trajectory under the control of the support 400. When the center of gravity is changed by the support roller 410 while the frame is moved, the deployment continues by the weight of the frame without lifting force of the pulley, from which the pulley regulates the lowering of the frame. At the same time, the recoiler 120 installed in the hoisting machine operates and the force begins to accumulate and simultaneously buffers.

As the pulley draws the belt fastened to the lower connection point, the development of the frame continues and regulates the belt fastened to the lower connection point of the frame to prevent excessive velocity development. In the deployment process, the guide tracks, support rollers, support arms, pulleys and bands are used to deploy the frame with minimal operating space and minimize the area of the entrance.

As the wheel passes the guide track, force is accumulated in the recoil 260 installed in the guide track. According to the development of the frame, the angle between the superstructure and the frame body changes within the given constraints and lowers the height of the ceiling space required for the deployment of the frame. In accordance with the development of the frame, the sliding car is moved in the orbit above the rear orbit of the frame and stops at the upper end 331 of the track. The frame changes its phase vertically by the action of gravity, belt, slide and support arm when the support roll is released. If the development of the frame continues, the slide is stopped at the upper end of the rear track, and the frame is developed in the vertical direction with the upper fixing point of the support arm as the apex by the support arm. It is pulled in the direction of the constraint surface and close to the constraint surface (walls, windows, etc.).

If the height of the ceiling has a flexible extension arm and joint support arm or flexible support arm, the length of the extension arm is extended and the folded or wound support arm due to the weight of the frame body and the display panel. As you develop, the frame will move further down.

When the viewing position (b) is reached according to the development of the frame, the wheel 310 of the frame reaches the viewing position fixing point 260 of the guide track and stops to form a first fixed point. At the same time, the support arm bears the weight between the slide and the superstructure seated at the rear track end of the frame and forms a second fixed point on the superstructure. Here, a third fixed point is formed by the coupling part 422 of the support arm and the sliding car, the upper fixed point of the sliding car and the rear track, and the weight of the frame and the display panel to stabilize the frame with three fixed points at the viewing position. Will be stuck.

The movement from the viewing position to the storage position operates in the reverse order and takes the greatest force in the initial stage of maneuvering. At this time, the repulsive force of the recoilers reduces the burden of the hoist and enables the operation with a small force.

The present invention is a device for receiving a display on the ceiling, can be used in the field of home appliances.
